  title: NutriCal Food & Nutrition Entity API
  version: '2.0'
  description: 'The NutriCal API powers apps, programs, and websites with NutriCal''s food and nutrition intelligence for the GCC and beyond: an ingredient database of 40,000+ foods (USDA + NutriCal proprietary), recipe management and nutrition analysis, recipe categories, meal-plan management with per-customer meal plans, and nutrient/allergen metadata used for Saudi FDA / GCC-compliant food labeling. Two public metadata endpoints require no authentication; entity-scoped recipe, category, and meal-plan operations are authenticated with an entity Access-Token; entity provisioning uses an organization API Key.'
